Here we have a fantastic example of a Rolex Air King Reference 5500, this piece is powered by the cal. 1520
 
The case size of this piece is approx 34mm not including the crown and the case condition is overall very good with only light signs of wear.
 
The dial and hands are in very good condition with only the very light signs of ageing that you might expect with a watch of this age.
 
The crystal is in mint condition.
 
The bracelet condition is very good and will accommodate a wrist size of up to just shy of 7.5 inches comfortably. (Extra links can be sourced)
 
The movement has just been serviced and is running well / keeping time accurately.
 
This watch has a serial 5,6xx,xxx so we can date it to 1978
